lNKlNG-RIBBON-ATTACHI NG MEANS.

SPECIFICATION forming part of Letters Patent No. 792,881, dated June 20, 1905.

' Application filed April 17, 1901. Serial No. 56,176.

To all whom, iv' fina/y concern:

Be it knownl that I, MURRY H. CHAPIN, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Inking-Ribbon-Attaching Means, of 'which the following` is a' In the accompanying drawings, Figure 1 is an elevation or plan view of an hiking-ribbon having applied thereto my improved attaching means and showing' the same as connected to the free ends of tabs or uninked strips secured to ribbon spools or reels. Fig. 2 is an enlarged central vertical section taken at the line X X of Fig. 1. of one of my improved hooks and one of the strips of gummed cloth to which it is secured and by which it is connected to the inkingribbon. Figs. I and 5 are plans of modifications.

In the several views the same part will be found designated by the same numeral of reference. v

1 designates a ribbon-spool such as is usually employed in type-writing machines, and 2 a tab or strip of uninked cloth such as is generally permanently secured at one end to the core of said spool and is free at its opposite end, so as to enable the end of an inking-ribbon, as 3, to be connected thereto in a detachable manner, so that it may be wound upon and unwound from said spool and when worn out from usage may be readily disengaged and be substituted by a new or fresh ribbon.

Heretofore it has been common to attach the ribbon ends to the tabs by means of pins and also by means of hooks. The latter are much better than the ordinary pins, because the connection may be made more conveniently and rapidly and without soiling the lingers to Fig. 3 is a plan view the same extent; but the prior hooks have proved unsatisfactory and objectionable, because as made and attached they would swivel or rotate in their loops or bearings and get out of true working position, and thus make it difcult for the operators to attach the hooks to the tabs and detach them therefrom. I have overcome' this objection by providing means for holding the hooks securely against turning movement and in true working position, and I have further improved the structure by the employment of gummed cloth instead of paper, Awhich has been used hitherto and which cannot be obtained strong enough to prevent the hooks from being torn out.

I prefer a hook of the duplex form illustrated#that is, one made of wire and provided at each end with a pointed hook A. The shank or bar portion 5, connecting said hooks, is preferably made integral therewith and also preferably lies in the same plane with said hooks. At one or more places in said connecting bar portion means are provided for preventing the hook or hooks from turning when the device is secured to a plain or uninked strip or holder 6. The said means consists of one or more bends, cranks, or projections 7, preferably formed in the wire of the bar portion and extending a suitable distance laterally or radially therefrom. The bends or projections are so located as that when one end of the strip 6 is turned over and gummed upon the body portion of itself it covers or embraces said bends or projections, as well as substantially the remainder of the bar portion 5 of the device. The strip 6 is preferably, although not necessarily, made of cloth or some suitable woven fabric having a previously-prepared gummed surface. (lndicated by the hatched lines at Fig. The said strips 6 are also of such length as that the end or portion opposite that embracing the hook thereof may be readily secured to one side of one end of the hiking-ribbon.

From the drawings, and from what has already been said, it will be apparent that the hooks or attaching devices are secured in position upon the previously-gummed strips 6 yillustrated at Fig. 2.

by laying them crosswise of the same, with their hook ends projecting beyond the side edges ofthe strip, and by then folding one end of the strip over the bar portion of the device and securing said end by causing it to adhere to the underlying portion of the strip. The parts of the strip are pressed firmly together and as close to the -bar portion as possible, as

When the hooked device has thus been secured to the gummed strip, it is held firmly in position and in substantially the plane of the fold and cannot turn in its loop or housing 8 on account of the presence of the offsets or bends 7 formed in the bar portion of the device, because any force applied to either of the hooks tending to turn the same is met and resisted by those portions of the strip which embrace said offsets or bends, and thus the hooks I are maintained always in proper position relatively to the strip 6 and cannot swivel or get out of true working position. Being thus permanently held, they may be more readily attached to the tabs 2 by digging their sharpened ends into the meshes thereof, as illustrated at Fig. l, and with much less liability of causing the hands of the user to become soiled than would be the case if the hooks could get out of true position and had to be adjusted and independently held during the attaching operation.

Inasmuch as the strip 6 is made of cloth, it is impossible for thebar portion of the duplex hook to pull through the loop under the strain of attaching the device and under the strain or pull of thc ribbon during use, while at the same time it is impossible for the bends or cranks to penetrate or break through the cloth under any force tending to turn the bar in its loop.

It is obvious that my improvement may be carried out in various other forms and with projections or stops of other shape and design, and hence I do not wish to be limited to the precise construction and form herein shown and described, although they are ones I have used in practice and have found entirely satisfactory. Instead of gumming the two plies of the cloth strip they may be sewed together, as by a transverse row of stitching 9, close to the pointsof the bends, (see Fig. 4,) and instead of using the strip 6 the hooks may, as in Fig. 5, be applied directly to the ends of the ribbon by folding the extremities thereof over the bar portions of the hooks and securing them by gum or stitching, as before explained; but while such a construction would embody that important feature of my improvement relating to the provision of means for holding the hooks from turning within their folds or loops it would, however, involve a sacrifice of the device which enables the ribbon to be handled with little or no lia- .hooks and bar portion being all in substantially the same plane.

2. The combination of an inking-ribbon, an uninked strip secured to the end thereof, and a `wire attaching device consisting -of a bar portion having bends or projections and ahook at each end, the said bar portion with its bends or projections being secured within a fold or doubled portion of said strip, and the said bar portion, hooks and bends or projections being all in substantially the same plane.

3. The combination with an inking-ribbon, of a gummed cloth strip secured at one end to one end of said ribbon, a wire attaching device comprising a bar having a bend or bends therein and a hook at each end, and secured to said strip by folding the opposite end of said strip over saidbar and gumming the same upon the body portion of the strip, the said bar and hooks being in substantially the same plane.

4:. The combination with an inking-ribbon, of the 'uninked gummed strip -6, and a wire attaching device comprising the end vhooks 4:4, the lintermediate bar portion 5, andthe bend or bends 7 secured withina fold of said strip,

allof said parts being in substantially the same plane.

5. An inking-ribbon having a duplex vhook secured thereto, the hook members projecting beyond the sides of the pa-rt which carries them and the shank being provided with one or more projections intermediate the hook members, to prevent the duplex hook from turning, the said shank, hook members and projection being in substantially the same plane.

Signed at Bridgeport, in the county of Fairield and State of Connecticut, this 15th day of April, A. D. 1901.
